Answer: The first electromagnet has a more powerful current than
the second
Explanation:
Since the two electromagnets contain the same types of magnets and wires. If the magnet In the first moves much faster than the second. Therefore:
The first electromagnet has a more powerful current than the second
Because the induced EMF is proportional to the induced current.
Where the induced EMF depends on the speed of the magnet according to the formula below
EMF = BVL
So, increase in speed of the magnet will cause more powerful induced current and emf
Hope it helped you.

Today this question is about science,or chemistry.
A. Acceleration is a correct answer. Acceleration is a rate of change in velocity.
It change in velocity/change in time. Next, to slope will be indicated by the acceleration.
B Change in position is a incorrect answer.
C. Velocity is a incorrect answer. Velocity is a displacement of an object during a specific unit of time. It can used two measurements are needed to determine velocity. It displacement or by the time. Displacement it includes a direction, so the velocity will also includes a direction. It can used speed with direction. Velocity it can be average velocity or an instantaneous velocity.

Answer:
true
Explanation:
this is the answer to this question
Answer:
1st t=d/s
2nd s=d/t
5th d=st
are all of the variations I came up with
Explanation:
the original formula for speed is s=d/t
then, I created a ratio of s/1=d/t and cross multiplied to find d=st
then, I isolated the t in one side by dividing by s on both sides.
